Despite a last-ditch attempt by Miami developer Renzo Renzi to stop the sale of his Brickell area site to a Coral Gables group, the transaction has been completed.

The $21.5 million sale to Watson Investigations LLC has closed, Hinshaw & Culbertson partner Steven Carlyle Cronig said. Cronig is Watson’s manager. He declined comment on the company’s development plans for the 33,927-square-foot site at the corner of Southeast Eighth Street and First Avenue.
